Model test evaluation of a frequency-domain procedure for extreme surge response prediction of tension leg platforms
A frequency-domain procedure for the extreme surge response prediction of tension leg platforms (TLP) under waves and current loading is presented and evaluated. The procedure incorporates both first- and second-order viscous and potential (inviscid) effects. The evaluation is based on results of hydrodynamic tests performed on a 1/60 scale model of a TLP. The tests were specifically designed to quantify the wave current interaction effects on surge. Therefore, the TLP model was tested under currents only (simulated by towing), waves only, and combined waves and current. The procedure is shown to perform well for predicting the extreme response in random waves and current except when groups of large waves are present. In this case, the extreme response is underpredicted. Areas in which this situation can be improved are identified.
